Lithium-ion battery separating film machine
The lithium-ion battery separating film production line made by our company has many years research,development,manufacture experience,its products has the function as follow:
(1)Having electrical insulation features ensure mechanical isolation of the positive and negative;
(2) Has a certain pore size and porosity, to ensure low electrical resistance and high ion conductivity, have a good permeability for lithium ions;
(3) Since the electrolyte is a polar organic solvent, the film must resistant to the electrolyte, has enough chemical and electrochemical stability;
(4) Good wettability of the electrolyte and has sufficient liquid moisture absorbent capacity;
(5) Has sufficient mechanical properties including puncture strength, tensile strength, but the thickness is as small as possible; good dimensional stability and flatness;
(6) Good thermal stability and good automatic shutdown protection performance.Power battery has higher requirements of film, usually use composite film. The film has small hot shrinkage or it will cause a short circuit, triggering a battery thermal runaway.Description on the new process of lithium diaphragm stretching
Key points of the new process: online heat treatment of materials does not need the oven link in the old process. After casting, the composite can be directly fed into the drawing machine.
Unwinding diameter: in the new process, one unwinding diameter can reach 1000MM (four layers), which can reach 32 layers. The unwinding diameter of the old process is only 550MM (four layers), and it is 20 layers.
Packaging and shipping:
Seaworthy packing material such as:Wooden case and PE film,etc for PP plastic polypropylene hollow sheet machine package.
